A commercial roof protects the whole building and keeps daily operations on schedule, so the system has to be right. Modified bitumen is one of the most popular choices for low-slope commercial structures, and Lankford Roofing & Construction LLC has installed it across Sherman and the Texoma region since 1937. It is an asphalt-based material proven to be among the strongest and longest-lasting options for flat and low-slope roofs.
Modified bitumen systems combine exceptional strength against foot traffic with puncture resistance against hail and abrasion. The reinforced fiberglass sheet and white-coated granular surface make the system both durable and energy efficient, with outstanding reflectivity. That makes it ideal for restaurants, stores, and warehouses where rooftop access is common.
Modified bitumen first became popular as a commercial option in the 1970s. It is called “modified” because plastics and rubber polymers are added to the asphalt, and glass or polyester fibers give it strength:
